Abstract: The present invention relates to a method and a control system for driving a three-strand brushless, electronically commutated electric motor (2), wherein a line AC voltage (UN) is rectified and fed via a slim DC link (8) with minimum DC link reactance as a DC link voltage (UZ) to an inverter (10) that can be driven to supply and commutate the electric motor (2). A pulsating DC voltage (UG) initially generated by rectifying the line AC voltage (UN) is dynamically increased with respect to its instantaneous values by a step-up chopper (18) in such a manner that the resulting DC link voltage (UZ) with a reduced ripple always lies above a defined limit voltage (U18/U1) over time. The control system consists of a network rectifier (6), a downstream slim DC link (8) with minimum DC link reactance and a controllable inverter (10) that can be supplied via the DC link and driven to commutate the electric motor (2). A step-up chopper (18) is integrated therein with a controller (20) designed in such a manner that, the pulsating DC voltage (UG) rectified by the network rectifier (6) is dynamically increased with respect to its instantaneous values in such a manner that the resulting DC link voltage (UZ) with a reduced ripple always lies above a defined limit voltage (U20/U1) over time. Stray inductances (Ls1-Ls3) of the motor winding heads present in the electric motor (2) are used as inductor (L) for the step-up chopper (18).

Abstract: A maximum value selection unit (50) receives battery voltage values (Vb1, Vb2) and outputs the maximum value thereof to a lower limit value limiting unit (54). A maximum value selection unit (52) receives required voltage values (Vm1*, Vm2*) and outputs the maximum value thereof to the lower limit value limiting unit (54). The lower limit value limiting unit (54) outputs a voltage reference value (Vh*) by limiting the value so as not to fall below an output value of the maximum value selection unit (50). Switching commands (PWC1, PWC2) are generated based on a control computation using a combination of a voltage feedback control element and a voltage feedforward element, and a control computation using a combination of a current feedback control element and a voltage feedforward element, respectively.

Abstract: Control mode switching determination is made as a part of a main loop (control period (Tm)) for overall control of an AC electric motor. Control period (Tc) of a rectangular wave voltage control mode is shorter than the execution period (Tm) of the control mode switching determination. When switching from the rectangular wave voltage control mode to PWM control mode is determined, change in voltage phase of the rectangular wave voltage is inhibited from the timing (time t0) of control mode switching determination until the next execution of the main loop, that is, until the timing (time t1) at which the control mode is actually switched, to maintain voltage phase of the rectangular wave voltage at the time of control mode switching determination. Consequently, in a drive controller for an AC electric motor allowing switching between control modes, control mode can appropriately be switched without making unstable the operation of the AC electric motor.

Abstract translation: 将控制模式切换确定作为用于AC电动机的总体控制的主回路（控制周期（Tm））的一部分。 矩形波电压控制模式的控制周期（Tc）比控制模式切换判定的执行期间（Tm）短。 当从矩形波电压控制模式切换到PWM控制模式时，从控制模式切换确定的定时（时间t0）直到主循环的下一个执行（即，主循环的时间t0）被禁止矩形波电压的电压相位的变化 直到实际切换控制模式的定时（时间t1），以便在控制模式切换确定时保持矩形波电压的电压相位。 因此，在用于允许切换控制模式的交流电动机的驱动控制器中，可以适当地切换控制模式，而不会使交流电动机的操作变得不稳定。

Abstract: The present invention contemplates a hybrid vehicle capable of changing an amount to be charged to an electric power storage device in accordance with whether it is externally charged. The hybrid vehicle includes a control device inquiring of an occupant of the vehicle whether the occupant has an intention to go to a charging location for example at home. If so, the control device sets a target value for the electric power storage device's amount of a state (SOC) to have a value smaller than when the occupant does not have an intention to go to the charging location. This allows as much energy as possible to be received at the charging location and a vehicle can thus be obtained that less depends on an internal combustion engine and contributes to environmental protection.

Abstract: A surge voltage generated by the switching operation of an IGBT element and voltage variation generated in an equivalent series resistance of a capacitor are superimposed on an input voltage of an inverter. The equivalent series resistance has a temperature dependence that a resistance value increases with a decrease in a capacitor temperature. The IGBT element has a temperature dependence that an element withstand voltage decreases with a decrease in an inverter temperature. When capacitor temperature is lower than a predetermined threshold value, a control device reduces an upper limit value of the input voltage by an amount corresponding to the voltage variation from its upper limit value at a high temperature, and controls a target voltage of a boost converter such that an output voltage does not exceed the upper limit value. Consequently, the allowable range of the surge voltage can be ensured.

Abstract: A controller for a vehicle including at least one motor driving wheels, an inverter driving the motor, and a boosting converter supplying a dc power supply current to the inverter, is provided with a control portion performing rectangular wave control and non-rectangular wave control on the inverter in a switched manner. The control portion has an emergency switching condition for switching control from the rectangular wave control to the non-rectangular wave control, as a determination reference, and when the emergency switching condition is satisfied while the rectangular wave control is being executed (YES at step S5), the control portion instructs the boosting converter to lower target output voltage (S7). Preferably, the control portion determines that the emergency switching condition is satisfied when a q-axis current supplied from the inverter to the motor exceeds a prescribed threshold value.

Abstract: An upper limit value setting unit of a control device conducts integration on the change in battery power, and determines whether the integrated value is lower than a preset first threshold value (negative value). When determination is made that the integrated value is lower than the first threshold value, and the battery power difference is lower than the second threshold value (negative value), the upper limit value setting unit sets Vup2 that is lower than the general Vup1 as the upper limit value of the inverter input voltage command.

Abstract: In a motor drive control system configured to include a converter capable of stepping up the voltage, when the locked state of MG2 operating as an electric motor does not occur (NO in S130), a voltage command value VHref for the converter output voltage is set according to respective required voltages of MG1 operating as an electric generator and MG2 (S140). In contrast, when the locked state of MG2 occurs (YES in S130), the voltage command value VHref is set to a limit voltage Vlmt or less for limiting the voltage step-up by the converter (S150, S180). When the locked state occurs, the converter output voltage is decreased and accordingly the DC voltage switched by the inverter is lowered, so that a switching loss at the switching device forming a part of the inverter is reduced and the temperature increase due to the heat generation can be suppressed.
